The Cockpit 389 Console\u0027s LDAP editor embeds a raw LDAP entry DN into a double-quoted shell command string executed via Cockpit\u0027s privileged (superuser) channel. LDAP DN syntax does not require escaping of shell metacharacters such as $, (, and ), so a DN crafted with command substitution executes on the host when a more-privileged Cockpit operator subsequently views that entry. This compromises confidentiality, integrity, and availability of the host. Exploitation requires both a delegated LDAP write privilege and a privileged operator viewing the crafted entry; neither precondition alone is sufficient.
